Added ac to my 3x3 tent....temps same

Im wondering if my ac infinity is pulling out the cold air. I placed a 4" duct into the bottom if my tent. I also have a passive 6" intake on the oposite side. My ac infinity was on level 3 keeping temps at 82 degrees. I added ac and temp is the same. I turned my ac infinity down to level 1 to see if it helps. Any advice? Thanks in advance.

What kind of AC unit? Keep one of the passive intakes and bump up exhaust
I tied into my central ac. My leaf surface temperature is 79 to 80 degrees. I have my nars hydro led approx 20" from canopy. Plants are starting week 2.

I don't have a tent setup yet. But here's my two cents.

What lighting are you using? If HID then you want that closed off from the tent. That airflow, in theory wouldn't be mixed with the air inside the tent, just pulls the heat from the hood. So it would be outside air, moving across lighting, then pulled out of the tent. Make sense?
That alone should help you manage your heat.

But wait, there's more....

Your HVAC (Air Conditioner) ducting should be mounted lower, at the bottom. As heat rises, the exit ducting at the top will pull the air out.
Typically, you'd have more blowers, one for the intake, then one on the exit. This equalizes the uneven pressures, if you have just one fan - pushing the air into the tent will create a positive pressure scenario that'll turn your tent into a "balloon" and the adverse would happen at the exit, sucking in the side walls. With this, you may just be able to use your homes pressure to feed the tent. BUT you'd need to get a inline air pusher, cheapo to help draw that air out of the tent. Could be hooked up to a sensor that only turns on when your HVAC is operational.

But what do I know?

Whelp, I certainly know how to NOT read prior comments. Just seen that you have a Mars Hydro LED. Hmm. that puts a small stick in the spokes for my idea. Unfortunately, I have no ideas when it comes to cooling LED lights other then moving air across them. Ill be following this thread for my own sake.

You realize it will only work when your a/c is in demand
Which for me is not when I run my lights
The whole AC nomenclature is misleading
I suppose you could make your home into a walk-in cooler :lol:
My ac runs very often living in a hot climate year round.

Mars hydro 4800 led.
My ac in at the very bottom of my tent. Exhaust at top. Its blowing in from my central ac which runs often.
I only have a passive intake other than the ac line. I do get negative pressure running my ac infinity exzaust on speed 3.
I do have a 4" ac infinity i could blow air into tent. Windering if that would help.
I just feel like my exhaust is pulling cooler air out. Hmmmm.

If your at a negative pressure now then adding in the smaller AC Inf. to push equalize this it will definitely help. As it sits now, your air exchanging is way off. Try adding in the additional fan to add some pressure back in, or add an inline pusher between your Air Cond and your tent.
Something like this.... Booster Fan

...and yes, what you're doing is adding cool air from the AC but drawing air from outside the tent and whatever cooled air and you're exhausting just as quickly as it's going in so you're not getting any real cooling from it.

I'd agree though, that you temps that are in the low 80's aren't a problem. I'm generally happy with stuff that's in the 79f-84f range.

With tents you need a stable lung room they sit in to controll temp and humidity. Youll have a helluva time just trying to heat or cool the tent directly.

Anyways, it sounds like your tent is within great parameters, no need for cooling.

Sounds like your temps are fine. During the summer I keep my ac set at 75 for a tent temp of 80. Big ass 15000btu window unit, gets the job done but eats electricity like a mf.
